Matlab function inside Simevents gives parse error

I tryed to write a simple Matlab function in Simevent system. The function is as follows:

_ _ _ *function [out_VFT, out_Time_In] = fcn(~,VFT,Time_In,Pcksize,weight,class,~,WFQ_DRR_MIX)
double VFT1=0;
double VFT2=0;
double VFT3=0;
double VFT4=0;
double VFT5=0;
double VFT6=0;
double VFT7=0;

if class==8||WFQ_DRR_MIX==1
  switch class
  case 1
          if VFT1>Time_In
          out_Time_In = VFT1;
          else
          out_Time_In=Time_In;
           end
out_VFT=out_Time_In+Pcksize/weight;
VFT1=out_VFT;

    case 2
            if VFT2>Time_In
            out_Time_In = VFT2;
            else
            out_Time_In=Time_In;
            end
out_VFT=out_Time_In+Pcksize/weight;
VFT2=out_VFT;

     case 3
            if VFT3>Time_In
            out_Time_In = VFT3;
            else
            out_Time_In=Time_In;
            end
out_VFT=out_Time_In+Pcksize/weight;
VFT3=out_VFT;

    case 4
            if VFT4>Time_In
            out_Time_In = VFT4;
            else
            out_Time_In=Time_In;
            end
out_VFT=out_Time_In+Pcksize/weight;
VFT4=out_VFT;

    case 5
         if VFT5>Time_In
         out_Time_In = VFT5;
         else
         out_Time_In=Time_In;
         end
out_VFT=out_Time_In+Pcksize/weight;
VFT5=out_VFT;

    case 6
            if VFT6>Time_In
            out_Time_In = VFT6;
            else
            out_Time_In=Time_In;
            end
out_VFT=out_Time_In+Pcksize/weight;
VFT6=out_VFT;

   case 7
            if VFT7>Time_In
            out_Time_In = VFT7;
            else
            out_Time_In=Time_In;
            end
out_VFT=out_Time_In+Pcksize/weight;
VFT7=out_VFT;

    end
else
    out_VFT=VFT;
    out_Time_In=Time_In;
end
end* _ _ _

I get the following error: Undefined function or variable 'VFT1 TO VFT7'. The first assignment to a local variable determines its class.I trying different solutions, but with no result. Pls, help.

You don't need to define VFT1:n as doubles with the double command, this is default:

VFT1 = 0;

What you're doing:

double VFT1=0;
>> ans
ans =
  86    70    84    49    61    48

Is actually converting the string 'VFT1=0' to it's ASCII numeric equivalent, storing it in the default variable, ans, and then having it overwritten on the next line..

Also, don't name a variable class as this is a very important MATLAB function.
